body took Nietzschès philosophy seri- ously and fashioned his life upon it? . . . It is hardly fair to hang a nineteen-year- old boy for the philosophy that was taught him at the university." In "Amok," Chris clearly aspires to be a postmodern Übermensch, speaking of his "will to power" and insisting that any- one who is "unable to kill should not stay alive." Yet these sentiments did not fully explain the murder of the un- known man in the novel, who, Chris says, had "behaved in- appropriately" toward him. Chris, alluding to what hap- pened between them, says teasingly, "Maybe he didn't do anything significant, but the most vicious Devil is in the details." If Balà s philosophy had justified, in his mind, a break from moral constraints, including the prohibition on murder, these pas- sages suggested that there was still an- other motive, a deep personal connection to the victim-something that the bru- tality of the crime also indicated. With Bala unable to leave Poland, Wroblewski and his team began to question the sus- pect's closest friends and family. Many of those interrogated saw Bala positively-"a bright, interesting man," one of his former girlfriends said of him. Bala had recently received a reference from a past employer at an English-instruction school in Poland, which described him as "intelligent," "inquisitive," and "easy to get along with," and praised his "keen sense ofhu- mor." The reference concluded, 'With no reservation, I highly recommend Krystian Bala for any teaching position with children." Yet, as Wroblewski and his men deepened their search for the "Devil in the details," a darker picture ofBalàs life began to emerge. The years 1999 and 2000, during which time his business and his marriage collapsed-and J ani- szewski was murdered-had been espe- cially troubled. A friend recalled that Bala once "started to behave vulgarly and wanted to take his clothes off and show his manliness." The family babysitter de- scribed him as increasingly drunk and out of control. She said he constantly be- rated his wife, Stasia, shouting at her that "she slept around and cheated on him." According to several people, after Bala 132 THE NEW YORKER, FEBRUARY II & 18, 2008 and his wife separated, in 2000, he re- mained possessive of her. A friend, who called Bala an "authoritarian type," said of him, "He continuously controlled Stasia, and checked her phones." At aNew Year's Eve party in 2000, just weeks after J anis- zewski's body was found, Bala thought a bartender was making advances toward his wife and, as one witness put it, "went crazy." Bala screamed that he would take care of the bartender and that he had "already dealt with such a guy." At the time, Stasia and her friends had dismissed his drunken outburst. Even so, it took five people to restrain Bala; as one of them told po- lice, "He was running amok." As Wroblewski and his men were trying to fix on a motive, other members of the squad stepped up their efforts to trace the two suspicious telephone calls that had been made to Janiszewski's office and to his cell phone on the day he disappeared. The public telephone from which both calls were made was operated with a card. Each card was embedded with a unique number that registered with the phone company whenever it was used. Not long after Bala was released, the telecommu- nications expert on the Janiszewski case was able to determine the number on the caller's card. Once the police had that in- formation, officials could trace all the telephone numbers dialled with that same card. Over a three-month period, thirty-two calls had been made. They in- cluded calls to Balàs parents, his girl- friend, his friends, and a business associ- ate. "The truth was becoming clearer and clearer ," Wroblewski said. Wroblewski and his team soon un- covered another connection between the victim and the suspect. Malgorzata Dro- zdzal, a friend ofStasiàs, told the police that in the summer of 2000 she had gone with Stasia to a night club called Crazy Horse, in Wroclaw. While Dro- zdzal was dancing, she saw Stasia talk- ing to a man with long hair and bright- blue eyes. She recognized him from around town. His name was Dariusz Janiszewski. Wroblewski had one last person to question: Stasia. But she had steadfasdy refused to coöperate. Perhaps she was afraid of her ex-husband. Perhaps she believed Balàs claim that he was being persecuted by the police. Or perhaps she dreaded the idea of one day telling her son that she had betrayed his father. Wroblewski and his men approached Stasia again, this time showing her sec- tions of "Amok," which was published after she and Bala had split up, and which she had never looked at closely. According to Polish authorities, Stasia examined passages involving Chris's wife, Sonya, and was so disturbed by the character's similarities to her that she finally agreed to talk. She confirmed that she had met Janiszewski at Crazy Horse. "I had or- dered French fries, and I asked a man next to the bar whether the French fries were ready," Stasia recalled. "That man was Dariusz." They spent the entire night talking, she said, and Janiszewski gave her his phone number. Later, they went on a date and checked into a motel. But before anything happened, she said, Janiszewski admitted that he was married, and she left. "Since I know what it's like to be a wife whose husband betrays her, I didn't want to do that to another woman," Sta- sia said. The difficulties in Janiszewski's marriage soon ended, and he and Stasia never went out together again. Several weeks after her date with Janiszewski, Stasia said, Bala showed up at her place in a drunken fury, demand- ing that she admit to having an affair with Janiszewski. He broke down the front door and struck her. He shouted that he had hired a private detective and knew everything. "He also mentioned that he had visited Dariusz's office, and described it to me," Stasia recalled. "Then he said he knew which hotel we went to and what room we were in." Later, when she learned that J aniszew- ski had disappeared, Stasia said, she asked Bala ifhe had anything to do with it, and he said no. She did not pursue the matter, believing that Bala, for all his tumultuous behavior, was incapable of murder. For the first time, Wroblewski thought he understood the last line of "Amok": "This was the one killed by blind jealousy." S pectators flooded into the court- room in Wroclaw on February 22, 2007, the first day of Balàs trial. There were philosophers, who argued with each other over the consequences of
